基于维思2.0的时空DLG数据质量检查方法

Methods of Quality Inspection of Spatio-temporal DLG Data Based on Weisi 2.0

基于探讨大比例尺数字地形图质量检查的内容和方法,通过抽样与实验的方法,利用武汉市测绘研究院自主研制的维思2. 0平台以及生产的1∶2 000时空DLG数据进行实验,阐述了该平台进行数据质量检查的内容与方法,并总结了该质量检查与其他传统DLG数据质量检查的不同之处。实验结果证明,利用维思2. 0进行数据质检,结果精确性和效率都较高。

Based on the discussion of the contents and methods of quality inspection of large-scale digital topographic maps,through the sampling and experimentation methods,we uses the WeiSi 2.0 platform which is independently developed by Wuhan Geomatics Institute and the 1∶2000 spatio-temporal DLG data for experiments.This paper illustrates the contents and methods of data quality inspection of this platform,and summarizes the differences between this quality inspection and other traditional DLG data quality inspection.The experimental results show that accuracy and efficiency of the data quality inspection results are very high with the use of WeiSi 2.0 platform.
